What is prostate cancer?
The prostate gland is found only in men. It is about the size of a walnut, and sits just below the bladder in front of the rectum. The urethra (the tube that carries urine from the bladder) runs through the prostate. The role of the prostate gland is to manufacture a fluid that is part of the semen (the fluid that contains sperm).
Prostate cancer is the second most common cause of cancer deaths among men. According to the American Cancer Society, an estimated 218,890 new cases will be diagnosed in the year 2007. The risk of developing prostate cancer increases significantly after the age of 65.
